Sound analysis reveals engine performance

A team of engineers at Ohio State University has developed a unique computer analysis method that extracts information about engine performance, driver's technique and racing team's strategy: the researchers use a computer to to sound pitches from race cars to calculate instantaneous speed and trajectory. From those basic data, the engineers then can calculate key things about vehicle and driver performance.

A team of engineers at Ohio State University has developed a unique computer analysis method that extracts information about engine performance, driver's technique and racing team's strategy: the researchers use a computer to “listen” to sound pitches from race cars to calculate instantaneous speed and trajectory.
From those basic data, the engineers then can calculate key things about vehicle and driver performance. These include:
